MACHINE FOR SHA-PING BOTTLE-NECKS.

SPECIFICATION forming part of Letters Patent No. 400,556, dated April 2, 1889. Application filed November 9, 1888. Serial No. 290,370. (No model.)

T0 a/ZZ whom. it may concern,.-

. Be it known that I, EDWARD H. EVERETT, of Ivewark, Licking county, Ohio, have invented anl Improved Machine for Shaping Bottle-Necks, of which the following is a specification.

The object of my invention is to provide certain new and useful improvements in bottleneck-shaping machines.

The invention consists in the details of improvement and the combinations of parts, that will lbe more fully hereinafter set forth.

Reference is to be had to the accompanying drawingsforming part of this specification, 1n which- Y l `Figure l is a side elevation, partly broken, of my improved machine. Fig. 2 is an enlarged detail view of a portion thereof, and Flg. 3 is a side elevation of a modification of my machine.

In the accompanying drawings, the letter A represents a base or guide plate, that is mountedupon suitable supports, a.

B is a spindle or shaft, that is journaled in bearings b d, supported by the base A. The spindle B is rotated as follows: At one part said spindle is providedwith a worm, e, that journaled in the supports a receives a nut or sleeve, D, having corresponding internal threads, or a pin that lits 1n said worm. This nut or sleeve D is secured to a longitudinally-movable arm, f, that projects from the base or guide plate A. To this arm f is secured a connecting-rod, g, that is pivoted to a crank, vh, on a shaft, c', suitably or otherwise carried. The shaft t' is driven by belt and pulley from suitable source or by other means. As the shaft t' rotates, the nut or sleeve D, through the connecting-rod f g and crank h, will be reciprocated without turning. As the sleeve D is thus reciprocated, its internal threads working in the Worm e Will rotate the spindle B alternately in opposite directions; but, if preferred, the spindle B could be r0- tated directly by belt and pulley or otherwise.

In order to ease the working of the threads between the worm e and nut D, and also for shaping certain styles of bottle-necks, I may give the spindle B longitudinal motion. rIo

accomplish this, I provide the bearing cl for the spindle B with an internal worm, b2, that meshes with a worm, d2, on the spindle B, as clearly shown in Fig. l. I prefer that the, Worm c be so cut with relation to the Worms b2 cl2 that as the sleeve D travels along the spindle B four inches the spindle will travel longitudinally one inch; but this relation of speeds may be changed to suit the requirements.

At the end of the spindle B, opposite the worin e, is placed a plug or core, E, that is adapted to enter the mouth of a bottle, j. At its inner end the plug or core E preferably has a plate or stop, Z, that limits the passage of the core into the bottle-neck. The base of the bottle j is held in a cup or snap, m, the handle or rod n of which is to berested upon supports or bearings o that are carried by a rod, 2, that extends longitudinally along the base A. When a bottle, j, is placed in position upon the core E, the neck of the bottle vis or may be passed through a ring or other shaped support or bearing, p, that is carried by the rod i2. When the bottle is in the proper position upon the core E, the body portion of the bottle at the neck will lit in the ring-sup port p, as shown in Fig. l. The supports 0 o and p are preferably vertically adjustable.

F F are shaping-jaws, that are adapted to straddle the bottle-neck, and also to rotate around said neck. The jaws F F are supported on or are continuations of levers q,

'that are pivoted to arihs r, that are carried by the spindle B.v The arms r may be secured directly to the spindle B, as shown in Fig. 3,

or they may be secured to a sleeve, s, that fits on the spindle B, as clearly shown in Figs. l and 2. When this sleeve s is used, I preferably secure it to the spindlel B by a pin, t, that passes through the arms r and said sleeve.

G is a sleeve that fits over the sleeve s and slides freely thereon, being guided by a screw or pin, u, passing from the sleeve G into a slot, o, in the sleeve s, as shown in Figs. 1 and 2. By this screw u the sleeve G is also carried around with thel spindle B and sleeve s. A shoulder, s2, on the sleeve s will prevent the sleeve G slipping off Athe same. The sleeve G preferably has a skelet-on extension that con- IOO sists of two rods, w, connecting the sleeve proper, G, with a ring, x, that encircles the sleeve s.

For the purposes of this speci tication I consider the parts G, w, and as one sleeve, which I term G To the sleeve G, or, more properly speaking, to the rods w, are pivoted links fg, that at their other ends are pivoted to the levers q. The rods i@ may be provided with a series of holes, hr2, into which the pivots of the links y may be placed, so as to give more or less movement to the levers q, as desired. Then the sleeve G is moved forward or into the position showin in Fig. l, the links y act to draw inward the ends of the levers q, and thereby to raise the jaws F in the bottle-neck; but when the sleeve Gis moved into the rearward position shown in Fig. 2 the links y act to press outward the outer ends of the levers q, and thereby crowd the jaws F toward the plug E and upon the bottle j, when it is in position on said plug or upon the plate Z, thereby limiting the movement of the sleeve G.

The sleeve G is moved along the spindle B, to open and close the jaws F, as follows: O11 the outer side of the sleeve G is an annular groove, e, that receives a pin, o2, on a lever, I, that is pivotally connected to the bearing b, as at p2. The lever I may be forked, if desired, to embrace the sleeve G, there being a pin, o2, for the groove e' at each end ofthe fork. The bearing b for the spindle B is made longitudinally movable when a longitudinally-movable spindle is used, and is guided in a slot of the base A, a plate, h2, being car- :ried by it below the base A, so as to hold and guide it on the base. To this sliding bearing b the rod Z2, that carries the supports o p, is secured. These supports by means of setscrews are longitudinally adjustable on the rod c2. A collar, J2, on the spindle B acts to push the bearing b forward as the spindle advances, thereby imparting motion by the rod Z2 to the supports 0 0 and p. In the return of the spindle B the sleeve s acts to push the bearing I) rearward to return the supports 0 o and p with the spindle. I also prefer to secure to the bearing b a rod, Z2, that extends parallel with the spindle B, passes through the arm f, and is guided in the stationary support m2 at the end of the base A. Upon the rod Z2, I place an adjustable collar, 'm2, that is adapted to be engaged by the arm f, as it returns in driving the spindle, this collar thereby acting to limit the travel of the arm f. The level I extends downwardly from its pivot 192 and is attached by a chain, q2, or otherwise to the arm f. The lever I is also connected by a chain or other IieXible connection, r2, with a weight, J, said chain r2 passing over a pulley, Z2, suitably supported by the framing of the machine.

My improved machine operates in shaping a bottle-neck as follows: The bottle j, while in a plastic state and having a plastic glass ring, a2, (see Fig. 1,) in position on the neck of the bottle, is secured in the cup or snap m.

The bottle-neck is then passed through lthe support or ring p and upon the plug E, while the jaws F are opened, the handle n of the cup m being placed upon the supports 0 o. The machine is now started by advancing the sleeve I), say, in the direction of the arrow a4, Fig. l, to turn the spindle B, the support h and its connections advancing under the inluence of b2 d2 with one-fourth the speed of f; hence the rear connection of the chain q2 advances much vfaster than the pivot p2 of the lever I, and the chain q2 will subsequently slacken, allowing the weight J to swing the lever I on `lts pivot, and thereby to move the sleeve G backward and close the jaws F upon the bottle-neck. The plug E while rotating within the bottle-neck acts to shape the in terior of said neck. While the jaws F are pressed against the bottle-neck and during their rotation with the spindle B they act to shape the bottle-neck. By the connec tion of the weight- J, chain r2, and lever I with the sleeve G a spring-like pressure is given to the jaws F. In other words, they are made yielding, so that when an uneven or raised part of the bottle-neck should come against the jaws they will be enabled to give or spread, and thereby prevent irregular work and damage. This is a very important feature, for if the jaws were rigidly held upon the bottle-neck there would be danger of making imperfect bottle-necks. As the sleeve D and the arm f move in the reverse direction to the arrow a, the chain q2 will draw upon the lever I, thereby moving the upper end of said lever in the direction of the arrow a to advance the sleeve G and open the jaws F to release the bottleneck. Thus it will be seen that the act-ion of the weight .I and arm f, through the medium of the lever I, serves to move the sleeve G and open and close the jaws F while the spindle B and the jaws F are rotating. By adjusting the chain up or down upon the lever I the distance the sleeve G should travel may be regulated. By lowering the chain on the lever I the pressure of the jaws on the bottleneck may be increased. When a longitudinally-movable spindle, B, is used and the lever I is pivoted to the movable bearing b, said' lever will always retain the proper position with relation to the spindle B and sleeve G; but the machine may be worked successfully without advancing the spindle B, if desired.

In the modification shown in Fig. 3 the spindle B does not advance, but is rotated in stationary bearings d. In this case the arms r are secured directly to the spindle B; but,

if preferred, the sleeve s could be interposed between said parts. In said figure the jaws ICO IIO

F are opened and closed by the sliding sleeve l 3 the spindle B is provided at the end opposite the plug E' with a bevel-pinion, L, thatmeshes with a bevel-gear, M, suitably journaled in bearings in the framing of the ma- 5 chine and driven alternately in opposite directions, one revolution at a time, by any suitable means. The wheel M or its supportingshaft carries a disk, N, to the rim of which is attachedv one end of the chain q2, the other 1o end of said chain being connected to the lever I, as shown, said chain passing over a sheave, g4, journaled kin bearings in the supports a. The chain q2 is also connected at one end to the lever I', and at its other end supports the weight J, said end passing over the pulley t2, journaled in the framing of the machine, as shown.

In using this style of machine the disk N is turned inthe direction of the arrow in Fig.

2o 3, whereby the chain 'q2 is slackened,which allows the weight J to draw upon the lever I,

' thereby moving the sleeve G rearward and closing the jaws F to form abottle-neck. [By

the time the disk N has made a half-revolu- 2 5 tion the chain q2 will have slackened as much as possible, and as the disk N continues to rotate it will wind the chain upon itself, thereby drawing the lever I and moving the sleeve G forward to open the jaws F. Vhen the disk 3o N has made its complete revolution, it is brought to rest.

In order to close the jaws disk N and gear-wheel M the spindle B is being rotated by the connection of the gearwheel M with the pinion L, whereby the interior of the bottle-neck is shaped by the plug and the jaws F F rotated around the bottleneck. The supports o o and p for the bottle in this case may be similar to those shown in Fig. 1; but they do not receive longitudinal movement, as the spindle B does not move forward. The weight and chain in this iigure have the same effect of giving an elastic or spring action of the jaws F upon the bottleneck as that described with reference to Fig. l.

It is evident that the weight J could be rel placed by a spring, if desired.

The chains q2 r2 may be replaced by any other suitable connection.

Having now described my invention, what I claim is* 1. `The shaping-jaws F F, combined with means, substantially as described, for revolving and for opening and closing them, the closing mechanism having a weighted member, I, which will allow the jaws, when closed and in the act of closing, to yield to pressure from within, as specified.

2. The spindle B, opening and closing jaws F, and sleeve G, jointed to said jaws, combined with the lever I, connected with the sleeve G and with the weight J on the lever I, andv means, substantially as described, for rotating the jaws F, all arranged to render the jaws yielding to internal pressure when closed and when closing, as specified.
